My Acoustat Model X’s come with forty watt mono blocks that have more than enough oomph to power them full bandwidth and with a crossover set at 100 hz, and a sub or two, it’s crazy good!
We should reject hard-to-drive speakers more often
Sorry I know this is a bit of a rant, but come on people!!
Too many audiophiles find speakers which are hard to drive and... stick with them!
We need to reject hard-to-drive speakers as being Hi-Fi. Too many of us want our speakers to be as demanding as we are with a glass of wine. "Oh, this speaker sounds great with any amplifier, but this one needs amps that weigh more than my car, so these speakers MUST sound better..."
Speakers which may be discerning of amplifier current delivery are not necessarily any good at all at playing actual music.
That is all.

Your reference to hard to drive Infinity Speakers brings back memories of my first "high end" purchase. In the early 70's I was at a hi-fi store in Palo Alto. They had the Infinity 2000A Electrostatic speakers (4 Ohm) on display playing a Cat Stevens album. To my young and naive ears they sounded spectacular. I don't know what amplifier they were using, but it was probably top quality, better than my Sherwood receiver at 60 watts a channel. I scraped up the money and bought the Infinity's. They sounded great even though my Sherwood was probably struggling to drive them. About a year later I traded them in, the speaker's power cords were quite inconvenient in my small apartment.
@ericsch: Small world! In 1071 I heard the 2000A at the same shop in Palo Alto: Sound Systems was it's name. They were running all their speakers (including the Infinity Servo-Static I's) with SAE electronics.The 2000A used a number of the wonderful RTR ESL tweeters, and were far more transparent that the AR 3a and Rectilinear III's I had been considering. I didn't have the $$$ for the 2000A, so got the 1001 instead. A year later I heard the Magneplanar Tympani T-I (also at Sound Systems) powered by ARC electronics, and it was a new world ;-) .
@bdp24 Yes, it was Sound Systems, a really nice shop. From reading your posts, we were living in the bay area about the same time. Winterland, Fillmore, Avalon Ballroom, etc.
I traded the Infinity's in for SAE speakers, also not very efficient. Then moved on to a Mac C-26 and a Crown amplifier, couldn't afford the matching Mac 2105.
Damn @ericsch, again! I too got a C-26, along with the MC2100, which was the version of the 2105 without meters. $499 vs. $649, iirc. $150 doesn’t sound like much now, but back then I guess it was! From there is was onward and upward: an ARC SP-3 and D-51 and D-75 amps, with Maggie Tympani’s. By 1972 Sound Systems was no longer pushing SAE and Infinity, but rather the hipper ARC and Magneplanars.
Yeah, San Francisco was (is?) a great town for seeing live music (but then so are L.A., NYC, and Austin). I saw the first appearances of Cream, Hendrix, and Jeff Beck, plus all the old guys Bill Graham booked into his venues, like Albert King.
With my musical tastes I kinda wished my Dad had stayed at Lockeed Aircraft in Van Nuys (he transferred to Lockheed Missiles & Space in Sunnyvale)---I then coulda seen Buffalo Springfield, Love, and all the other SoCal groups/bands emerging at the same time the hippie bands were up North. I saw The Dead and Airplane in ’67, but they’re not really my kinda thing.
